CHARLES G. BAILEY, OF YORK, PENNSYLVANIA.

COAL-SIFTER.

SPECIFICATION forming part of Letters Patent No. 542,514, dated J' uly`9, 1895.

Application filed March 18, 1895. Serial No. 542,194. (No model.)

To @ZZ whom it may concern,.-

Be it known that I, CHARLES G. BAILEY, a citizen of the United States,and a resident of York, in the county of York and State of Pennsylvania,haveinvented certain new and useful Improvements in Coal-Sifters; and Ido hereby declare that the following is a full, clear, and exactdescription of the invention, which will enable others skilled in theart to which it appertains to make and use the same,l

reference being had to the accompanying drawings, which form a part ofthis specification.

My invention relates to improvements in coal-sifters for separatingunburned coal or cinders from ashes, and its object is to provide animproved device whereby I secure important advantages with respect tosimplicity and economy in construction and efficiency in use. i

The invention consists in the novel construction and combination ofparts hereinafter fully described and claimed.

In the accompanying drawings, Figure lis a central longitudinal sectionof a coal-sifter constructed in accordance with my invention. Figs. 2and 3 are detail views, and Fig. lis a perspective view, of the hod.

In the said drawings, the reference-numeral l designates a rectangularash-pan, which Y forms the base of the sifter, provided on its underside with wooden cleats 2, secured thereto by nails or other fasteningdevices. The

rear edge of the pan is turned or bent over inwardly, forming a curvediiange 3, with which engages a similarly-formed flange on the lower endof the screen-box, hereinafter described. The pan is also provided witha bail 4, by which it may be transported from place to place,and theside and rear upper edges of the pan are wired to strengthen the same.

The numeral 5 designates the screen-box, rectangular in form, and havingits lower sides and ends bent or turned inwardly so as to readily iit inthe upper part of the ash-pan, and the sides and rear end a shortdistance above the bottom are provided with ribs 6 to prevent the boxfrom being inserted too far within the pan. The rear lower edge of thebox is bent or turned outward, forming a curved flange 7, which isadapted to engage with flange 3 and hold this end of the box in place, ahook 8 and catch 9 being provided at the other end of the boxand pan.The front end of the box is formed with a rectangular opening, the sidesof which are bent outward at right angles, forming iianges I0 forpreventing the escape of dust, as hereinafter described. i

The numeral I2 designates a vibrating screen consisting of a frame openat its outer end and having inwardly-extending flanges 13 at thesidesand rear end, while at the front or outer end it is provided with atransverse plate 14 secured to the side flanges 13. The screen proper,consisting Aof a ,rectangular piece of wire-cloth, rests upon saidflanges and plate' and is secured in place by means of metal strips l5and screw-bolts and nuts 16 and 17. By this means, when the wire-clothis worn out or damaged4 it can be replaced by a new piece by simplyremoving said strips. This can bedone by any one,'it not requiring theservice of a skilled mechanic for such plurpose.

The delivery end ofthe screen is supported upon a vibrating bail 18,consisting of a piece of wire having-its ends bent upwardly at rightangles, forming arms 19, the extremities of which are bent into hooks20, which engage with eyes 2l connected with screw-bolts 23. The screenis not secured to the bail, but simply rests thereon. `To the feed endof the screen is secured an arm 24, which passes through a slot in theend of the screen-box and is connected withv the lower end of a verticallever 25, which is pivotally connected with an upwardly-extending bar26, which also serves las a brace for the hopper. The numeral 27designates a funnel or inverted cone-shaped hopper provided with a cover28. This hopper is located near the feed end of the screen-box so as togive a long travel to the cinders on the screen. The lower end of thehopperpasses through an opening in the top of the screen-box, extendinga short distance below the same, and is provided with a collar 29,secured thereto by rivets'SO. This collar at its upper end is formedwith an annular flange 3l, which abuts against the nnder side of the topof the screen-box and not only prevents the hopper from beingaccidentally pulled out but makes a dust-proof ICO joint. The hopper issupported in place by the brace-bar 26 and also by brace-bars 32, thelower ends of Which are secured to the screen-box by the screw-bolts 23.

The numeral 34: designates a hod for receiving the cinders and unburnedcoal as they come from the screen. It consists of a rectangular-shapedbox with an inclined top, having an opening in its inner upper end, andis provided with a handle 35. At each side this hod is provided Withhooks 36, Which engage with lugs 37 on the screen-box, by which the hodis secured thereto.

The operation Will be readily understood. The ashes are placed in thehopper, which is then closed by the cover 28. The screen is now vibratedback and forth by the lever causing the ashes to fall through the meshesof the screen, while the cinders and unburned coal Will pass to thedelivery or discharge end of the screen and fall into the hod. Whendesired the hod can be readily disengaged from the screen-box and thecontents dumped into a stove or other receptacle. By the conicalorfunnel shape of the hopper the ashes are automatically fed to thescreen and clogging of the same prevented, so that a fresh supply isconstantly being fed to the screen; and by reason of the hopper beinglocated nearvthe feed end of the box and discharging on the feed end ofthe screen the cinders will have a long travel on the screen, insuring athorough removal of the ashes. The flanges at the front end of thescreen-box project into the hod when the latter is in place, thuscausing any dust to be carried into the hod and the escape thereof atthe joints vbetween the hod and the ash-pan and screen-box is prevented.

The entire machine, with the exception of the wooden cleats andoperating-lever, is made of metal Without the use of solder, and all thejoints are dust-proof, thus avoiding many of the defects incident tocoal-sifters of the ordinary construction. The hod and ashpan can bereadily disconnected from the screen-box, and the parts generally are soconstructed that they may readily be removed and replaced by others incase of injury or damage to the same. K

It will be noticed that the hod is formed with vertical sides and endsand an inclined top and an opening in its inner upper side, thusrendering it Very convenient for dumping thecontents into a stove.

\ Having thus fully7l described my invention, what I claim is- Y In acoal sitter, the combination With the ash pan, the removable screen-box,and the vibrating screen, ot' the funnel-shaped hopper, projectingthrough an opening in the screen-box and provided, at its lower end,with a collar having its upper edge turned outwardly, forming a flange;substantially as described.

In testimony thatI claim the foregoing as my own I have hereunto affixedmy signature in presence of two witnesses. Y' Y CHARLES G. BAILEY.'
